Convertible Header Seal Retainer

I'm getting close to redoing my top, but before I start I need to figure out what to do with my header seal retainer. It is in no condition to re-use once I remove it. Will the top remain attached to the header bar when I remove the retainer? I'd like to remove the retainer so I can begin to create a new one and still be able to use the car without the top flying off.
